AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
912 AM MDT TUE SEP 3 2013

.SYNOPSIS...HIGH PRESSURE OVER THE CENTRAL ROCKIES AND A UPPER
TROUGH OFF THE PACIFIC NORTHWEST COAST WILL MAINTAIN A FAIRLY
MOIST SOUTHERLY FLOW ACROSS THE REGION THROUGH MIDWEEK. A MODEST
DRYING TREND WILL DEVELOP FOR LATE IN THE WEEK MAINLY NORTH.

&&

.DISCUSSION...MID LEVEL RIDGE CENTERED OVER THE COLORADO ROCKIES
COUPLED WITH AN UPPER LOW SPINNING OFF THE PACIFIC NORTHWEST COAST
AT ABOUT 45N 130W REMAIN DOMINANT FEATURES FOR NEXT FEW DAYS. AS A
RESULT...A MOIST SOUTHERLY FLOW REMAINS ACROSS THE GREAT BASIN
TODAY. GOES DERIVED PW VALUES ARE GENERALLY AT OR ABOVE AN INCH
ACROSS THE FORECAST AREA WITH POCKETS OF 1.5 AND GREATER VALUES
JUST TO THE SOUTH AND WEST.

VORTICITY CENTERS ROTATING AROUND THE LOW CONTINUE TO STREAM
NORTHWARD WITH THE FIRST OVER SOUTHWEST UTAH/SOUTHERN NEVADA
FOLLOWED BY A WEAKER CENTER OVER SOUTHERN CALIFORNIA. THE FIRST
OF THESE CONTINUES TO MAINTAIN CONVECTION OVER SOUTHWEST UTAH.
THIS BAND OF SHOWERS AND THUNDERSTORMS IS MOVING VIRTUALLY
NORTHWARD AT THIS TIME AND IS EXPECTED TO TAKE A TURN TO THE
NORTHEAST THIS AFTERNOON WHEN IT REACHES CENTRAL UTAH. BY LATE
AFTERNOON AND INTO THE EVENING THIS FEATURE WILL SPREAD INTO
NORTHERN UTAH AND WILL HAVE TO RE-EVALUATE POPS FOR THAT AREA IN
AFTERNOON PACKAGE. THE SECOND FEATURE ONLY SHOWS UP IN THE
SATELLITE WATER VAPOR IMAGE AND NOT IN THE MODELS...SO WILL HAVE
TO SEE HOW THAT ONE PLAYS OUT...AS MODELS INDICATE SUBSIDENCE
WHICH MAY LIMIT ACTIVITY OVER THE SOUTHWEST. RADAR AND IR
SATELLITE IMAGE SHOW LITTLE ACTIVITY OVER SOUTHERN NEVADA...AT
THIS TIME...BUT WILL HAVE TO MONITOR THAT AREA AS WELL.

&&

.AVIATION...EXPECT SURFACE WINDS AT THE SLC TERMINAL TO REMAIN
SOUTHERLY THROUGH AROUND 20Z THEN TURN NORTHWEST. THERE WILL BE A
30 PERCENT CHANCE OF SHOWERS AND THUNDERSTORMS AFTER 20Z. ANY
THUNDERSTORM THAT SHOULD HAPPEN TO IMPACT THE TERMINAL WILL ALLOW
ERRATIC WINDS...BRIEF HEAVY RAIN...AND CEILINGS BELOW 7K FT MSL.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...NONE.
WY...NONE.
